Spectral gamma-ray logging report for the six new characterization boreholes in the 100-FR-1 operable unit

摘要

Six characterization boreholes were drilled, sampled, logged, and abandoned in the 100-FR-1 Operable Unit. The geophysical logging was carried out with the Radionuclide Logging System (RLS) to determine the levels of radioactive contaminants in the subsurface. Five of the six boreholes penetrated contamination that was successfully assayed with the RLS data.
